What is the main conflict in Shooting an Elephant? Is it external or internal or both?

The main conflict surrounds Orwell's reluctance to shoot an elephant that the Burmese villagers claim is nuisance. On a broader scale, the conflict revolves around British imperialism around the world during this era. There is both external and internal conflict here. Orwell doesn't want to be a part of the imperial force yet has responsibilities because he represents it.
